WASHINGTON (CNN)–On his 50th birthday, Massachusetts Republican state Sen. Scott Brown announced his intentions to run for the late Sen. Ted Kennedy's vacant Senate seat.
Characterizing himself as a Washington outsider, Brown spoke directly to the people of Massachusetts.
"Already, my opponents have started pandering to the special interests, promising to support their pet projects," Brown said. "That's not the way I operate. Because I don't owe anybody anything, I'm free to tell the truth and fight for what's right for all of the people of Massachusetts, no matter their political party."
Brown said he has a history of bipartisanship as a three-term state senator and former three-term state representative, and spelled out his "core" beliefs.
"I believe that government is getting too big and that the federal stimulus bill made government bigger instead of creating jobs as was supposed to happen," Brown said.
The veteran legislator made his announcement after former Bush administration Chief of Staff Andy Card, dropped out of the race late Friday and encouraged Brown to run for the seat instead.
Another conservative name that's been mentioned is that of former Red Sox pitcher Curt Schilling.
On the Democratic side, Massachusetts Attorney General Martha Coakley has already announced her plans to run for the seat.
Kennedy, 77, died on August 25 after a year-long battle with brain cancer. He had served in the Senate for nearly 50 years - most recently winning reelection in 2006.
